The serial port can be used to control the Visualizer through an external device, like a
remote control system for a whole conferencing room.
Please note that DecimaI-Codes (=ASCII-Codes
or Hex-Codes) must be sent as one single byte
(e.g. 199 and not: 1 + 1 + 9) !
Between sending codes should be a break of
250ms minimum !
Switching to playback of a video recorder
WolfVision Visualizers do not have an input switch because the following method of
connecting a video recorder is much easier and requires no switching at all:
Connect the video output (12) or the Y/C (S-VHS) output (13) of the Visualizer to the
according input of the video recorder. Connect the video or Y/C (S-VHS) output of the
video recorder with the input of your monitor or video projector.
When the video recorder is switched to "Play", the picture of the video recorder
is shown (without any separate switching):
It can also be used to control the Visualizer through a computer. A special Windows-
software for PC is available from WolfVision.
